This high performance 4 cycle, SAE 25W-40 oil is uniquely formulated with a marine additive to suit all horsepower outboard engines.

This outboard engine oil protects the internal engine components against the harmful effects of corrosion, delivers superior friction and wear protection and reduces piston ring deposits and scuffing and scoring of internal engine parts.
